Geothermal energy is thermal energy generated and stored in the Earth. Thermal energy is the energy determining the temperature of matter. Earth’s geothermal energy originates from the original formation of the planet (20%) and from  radioactive decay of minerals (80%) The geothermal gradient, which is the difference in temperature between the core of the planet and its surface, drives a continuous conduction of thermal energy in the form of heat from the core to the surface

From hot springs, geothermal energy has been used for bathing since Paleolithic times and for space heating since ancient Roman times, but it is now better known for electricity generation. Worldwide, about 10,715 megawatts (MW) of geothermal power is online in 24 countries. An additional 28 gigawatts of direct geothermal heating capacity is installed for district heating, space heating, spas, industrial processes, desalination and agricultural applications

Geothermal power is cost effective, reliable, sustainable, and environmentally friendly, but has historically been limited to areas near plate tectonic boundaries . Recent technological advances have dramatically expanded the range and size of viable resources, especially for applications such as home heating, opening a potential for widespread exploitation. Geothermal wells release greenhouse gases trapped deep within the earth, but these emissions are much lower per energy unit than those of fossil fuels. As a result, geothermal power has the potential to help mitigate global warming if widely deployed in place of fossil fuels.

The Earth’s geothermal resources are theoretically more than adequate to supply humanity’s energy needs, but only a very small fraction may be profitably exploited. Drilling and exploration for deep resources is very expensive. Forecasts for the future of geothermal power depends on assumptions about technology, energy prices, subsidies, and interest rates.

Until recently the condition of the electrical energy supply in a number of sub national electricity system is still a deficit. To ensure the supply of electrical energy, up to 2018 additional power required of about 57 500 MW or 5750 MW per year. For the government after the project held a Crash Program Phase I targeted Electrical operation in 2010, followed by phase II ( 2010 – 2014 ).

Initially the 2nd Fast Track Program PLN plans to build a government and a number of renewable energy-based on electricity generation, but due to the development of renewable energy facilities do not have adequate preparation, a number of projects in the 2nd Fast Track Program continue to be dominated by coal power plant.Unpreparedness, These include the development of PLTP associated with human resources, technology and capital. For example, from five geothermal working areas are handed over to the five penprov center, only one penprov namely West Java are already realizing the development of geothermal energy, namely PLTP Tangkuban Parahu to the auction stage.

However, the progress of geothermal development in Phase II of the 10,000 MW is significant both in terms of installed power and scope of the work. It also did not rule out the possibility of investors to develop geothermal energy in the working area available, as this is the government agenda in RUKN (National Electricity General Plan) and RUPTL 2008-2027 (Master Plan of Electricity Supply) 2008-2018.

Indonesia has the potential to become the largest user of geothermal energy. Based on the exposure to the Head of the Geology Mineral Resources, the total potential of geothermal energy is currently about 28.5 GWe spread across 265 locations, or the equivalent of 12 billion barrels of oil a 30-year operating period. The new geothermal utilization realized by 1189 megawatts (MW) will be increased to 4,000 MW by 2015, or about 40 percent of the 10,000 MW power project. If realized, Indonesia is more potentially abundant than America with the power of 2900 MW of 2,000 MW and the Philippines.Currently, Indonesia is the third geothermal users after the United States and the Philippines.

Has compiled a report with the government’s policy development activities related to geothermal energy, it is hoped all parties would be more objective in moving and business conditions to take more care of geothermal development in Indonesia, given the importance of geothermal energy as a major alternative fuel to replace the role of electrical energy.
